Collaborative Glaucoma Survey

Abstract

A number of institutions, including The Johns Hopkins University, are participating in a collaborative study of chronic simple glaucoma. It has been estimated that there are 800,000 persons in the United States who are unaware that they have glaucoma. The disease produces blindness in about 3400 persons each year. Preliminary findings of the survey are presented. When tonometry, tonography and the water-drinking test have been well evaluated in the early diagnosis of chronic simple glaucoma, an efficient screening program can be designed and much visual disability prevented.
